There are often debates among motorists about whether it is necessary to warm up an injection engine. For example, abroad, some drivers start driving with a cold engine. This is largely due to environmental concerns. Nevertheless, if you delve into the essence of the issue, you can understand that it is necessary to warm up the engine, but for a short time.
The conventional wisdom that injection engines do not need to be warmed up is quite wrong. In everything you need to know when to stop. If you start moving with a cold engine, you can quickly ruin the cylinder-piston system. Therefore, in the cold season, it is recommended to warm up the engine for at least 1-2 minutes. In this case, it is worth paying attention to the smooth operation of the engine. The turnover should be minimal and stable. If it does not work, adjust the idle speed. In no case do not press "gas to the floor", otherwise then you will have to do overhaul of the engine. During operation at low temperatures of both the carburetor and the injection engine, the wear of the parts of the piston group increases sharply. This is due to poor vaporization of the fuel. Corrosive wear is also accelerated. In turn, this is due to the fact that the coolant temperature is below 60 degrees Celsius. This leads to the formation of condensation. Water vapor and sulfurous gases contained in combustion products lead to the formation of an electrolytic film. Condensation also gets into the oil, which leads to the formation of sticky deposits that clog the passages and oil filters. The negative temperature of the running injection engine also reduces its power. This happens due to incomplete combustion of gasoline. The viscosity of the oil increases, as a result of which the cost of useful power increases, which goes to overcome the frictional forces of the pistons. All these factors are directly related to the quality of the lubricant. If you want your engine to run for as long as possible, then it is better not to skimp on it. For an injection engine, synthetic oil is best. It has a fairly high fluidity as well as penetrating power. These characteristics allow the deposits that form on the internal surfaces of the engine to flake off. Unfortunately, mineral oil does not have the same ability. If the fuel-air mixture correction system in an injection engine is working properly and synthetic oil is filled, then warming up the engine at idle speed can take only a few seconds in summer and up to two minutes in winter. The engine needs to be warmed up only to operating temperature, waiting for the oxygen sensor to warm up and the oil pressure in the system returns to normal.
